Pollinating for seeds

say i bought a 10 pack of seeds and i keep a male and pollinate some females now does this make the seeds an F1 and will these plants grow just as vigorous as there parents. Also if i keep on taking a male and pollinate its sibling female and do this generation after generation will the plants be so inbred that it will lose potency, vigor and so on.
thanks

wow....you are making THIS your first post!?

Im impressed as well. Dont know the answer but im impressed.

I got this here: ENOBLING - BREEDING - F1, F2, F3, F4, F5, F6, Weed Cannabis Grass Pot Marihuana Marijuana Hemp Seed Seeds

this was the first thing that came up that was fairly easy to read/was encapsualted to the point where it was somewhat understandable.

there is tons more info out there. Search for Robert. C. Clarke> marijuana> marijuana genetics for more info than most laymen can comprehend...

a few paragraphs down it goes into F1..F2..backcrosses..etc. and what the basic effdects of those are an the plant/the offspring..etc.

happy readin....

PROPERTIES
At the moment of fertilization the chromosomes of the female will connect with the chromosomes of the male. In this way 10 couples of chromosomes are created. On everyone of these chromosomes a number of genes a situated. The two chromosomes that make a couple have genes on the same places (loci). Such a gene on a locus consists of a property (allele). These properties (alleles) determine how the plant will look, grow, smell, bloom, and so on. If now on both chromosomes of a couple, the same property (allele) will be at the same place (locus), then the plant will show this property. In this case is said that the plant homozygous is for this property. If we have to do with different alleles then the dominant allele will determine the property while the property of the recessive allele will remain hidden. The plant is then heterozygous for this property.
TRUE BREEDING
If you buy a package of seeds and let nature do its way, then of course you will have offspring. And if you let these children have children, and so on........ In most cases the plants will start to look differently. Brothers and sisters will not look alike anymore. But in the event that the children continue to look like their parents we speak about a "true breeding strain". True breeding arises if the plant is homozygous on the important properties. This can happen by natural selection or by selective breeding. In both cases plants are taken away that do not meet the requirements. If the work has been done by natural selection then we talk about a "pure bred". These kind of plants then grow in a certain region. But normally we have to do with stabilized hybrids (products of crossbreeding). Known (more or less) true breeding strains that are developed by selective cultivation are: Skunk # 1, Haze and Shit.
INBREEDING
If you want to preserve the properties of a certain plant, very often this is done by inbreeding. By just backcrossing the children with the mother and later grandmother, these children will more and more look like the mother. After 6 times of backcrossing the plant will look very much like the (grand, grand.....) grandmother, whereas after 20 time of backcrossing the new plant will be genetically almost identical to the (grand, grand.....) grandmother. A much-made error is that growers think that in this way they will create a plant that will be on all important points homozygous and therefore true breeders. This is not the case! The plant that is created will genetically be like the (grand, grand.....) grandmother. And if this grandmother was no true breeder her offspring will also not be like this. If you want to create a stable line you need to use selective breeding for a number of generations.
HYBRID
By crossing two not related plants you will create a hybrid. These newly created plants are called F1. If the F1 plants are backcrossed to the mother then their offspring often will be called F2. Also F1 crossings between brothers and sisters are called F2 and sometimes even crossings between F1 plants of different lines are called F2. I presume however that, in most cases when breeders are talking about a F6, they mean by this that the plant was backcrossed for 6 generations, this to reinforce the properties of the mother. But be aware, this plant will probably not be stable. Even not if it is a F20. What you best can do is to select the plants that you like the most and use their clones for growing and blooming.
THE STRENGTH OF THE HYBRID (HYBRID VIGOR)
With "HYBRID VIGOR" is meant something like the strength of the hybrid. This is however only the case with a crossing of two stable plant lines (the plant is then on important properties homozygous and therefore true breeding). The F1 plants that you produce in this way will be all identical and very strong. Because of this, an enormous improvement on certain characteristics can arise. So it can be for example that these F1 plants grow much more rapidly or produce bigger buds then their parents. Another advantage of this F1 is that all plants will be identical. Selection of the best plants is of course not needed anymore. The strength of the hybrid will however decrease if you go on with breeding. A F2 is therefore qualitatively lesser then the F1. This because of the recessive alleles that nicely hided in the F1 and can come forward in the F2. Furthermore the offspring of F1 plants will no longer be identical.
